When Romain Chancel first encountered this duplex at the top of a 1970s block in Neuilly (an elegant district on the outskirts of Paris), it was suffocating under an old-fashioned carpet and neo-17th-century woodwork.

Upstairs, Romain has smartly included a stylish home bar in the winter-garden room, a space that, in the afternoon, is bathed in golden light on all sides. It’s the perfect spot to enjoy the apartment’s crowning glory: the roof terrace, which Romain remembers as being a ‘real virgin forest’ when he first encountered it.
